Description

Chart recording thermometers are ideal whenever a record of temperature variation versus time is required. The thermometer is available in two different time ranges. The L5145 records up to 24 hours while the L5146 records up to seven days. The temperature range on both are -40°F to 160°F with an accuracy of ±2% of full scale range. Since the instruments are spring activated, the instrument will operate in extreme temperatures where batteries fail. The sensor is constructed of ASTM type TM-2 bimetallic alloy which is heat treated for permanent calibration. The thermometers are furnished with an initial supply of 100 paper charts and clock key.
